post_call is a small tool which is able to send a HTTP request to your AVM FritzBox 7050, which will then call a number you provide to post_call as a command-line parameter and using a interface (phone port number) you also provide as a command-line parameter.

After FritzBox has called the number, your phone will ring when the person called is on the line. This can be useful if you want to integrate automatic calling from your electronic phonebook.
